I'm confused,
I *need* Internet Explorer to run SCIRRA's software?
I purposely gutted IE from this system. I don't want that on here, and if your program relies heavily on it, I probably will not purchase it.
Construct 2 only uses it to show the start page, which is rendered in HTML. It doesn't use it for anything else at all, it's just because IE is the only browser engine that can be assumed to always be installed.
How about this? Set the registry key 'HideStartPage' to the DWORD 1 in:
HKEY_CURRENT_USER\Software\Scirra\Construct2\Preferences
Then restart Construct 2 and it should skip loading the start page entirely. If the start page is the problem, that should fix it.
